There’s no doubt the Calgary Flames’ rivalry with the Edmonton Oilers is still going strong.

All you needed for proof was a machine to measure the decibels at Rexall Place during the Battle of Alberta taking place Saturday on Hockey Night in Canada.

By the three-minute mark, the noise was deafening — thanks to a pair of Oilers goals in that short span.

By comparison, the silence was stunning after Mikael Backlund scored his first of the season on the powerplay midway through the third period to lead the Flames to a 5-3 victory.

“I’m sure the crowd thought we were gonna take a beating,” said a smiling Flames captain Jarome Iginla, who set up three goals in the come-from-behind victory in his hometown.

The beating never materialized, and the noisy celebration was shortlived. After a Flames timeout with 57 minutes left, the visitors climbed back over the course of the night, getting strong all-around performances from their key players.

Iginla led the charge offensively.

Rene Bourque contributed a goal and an assist to help tie things up in the first period, blocked a couple of shots late in the game on the penalty kill, and beat out an icing to keep the puck deep in Oilers territory in the dying moments.

Jay Bouwmeester logged a jaw-dropping 10-plus minutes of shorthanded playing time amid his near half-hour on the ice.

Defenceman Derek Smith scored a tying goal in the third period, 44 seconds after the Oilers took the lead for the second time.

A pair of powerplay goals was only overshadowed by keeping the Oilers off the board for their dozen minutes with an extra man.

And Backlund netted his first of the season after a rocky first 10 games, giving the visitors their first lead of the night on the powerplay, pushing Iginla’s soft pass up the middle through Nikolai Khabibulin’s pads.

Olli Jokinen’s empty netter — his second goal of the night — capped off a crazy contest that featured some awesome saves, workmanlike goals and back-and-forth momentum swings from the drop of the puck.

“It feels good. Especially the game-winner, too,” said Backlund, who tweeted earlier in the day he thought something good was going to happen but admitted later he wasn’t predicting his slump-busting goal.

“I was just happy. A big relief. When you’ve got a lot of expectations coming in and then you don’t score in a lot of games, you get a lot of pressure on yourself.”

The pressure was on the Flames early with Lennart Petrell tipping a Darcy Hordichuk shot past Flames netminder Miikka Kiprusoff just 2:19 in and Sam Gagner sliding a long screened shot into the net 41 seconds later.

The rafters shook as the crowd went wild, and head coach Brent Sutter called his timeout.

“Yeah. The fans were excited,” Backlund said.

“Play against us and you go up two, of course you’ll have excited fans.

“Our fans would be pretty crazy, too, if we were up two against Edmonton.

“It’s better to let two goals in three minutes than three in the last minutes.”
